Since batteries are subject to ageing, the analysis of lifetime values of different failure modes results in time-dependent failure rates of different magnitudes. The failure rates of the individual failure modes develop with different shapes over time, which allows their ageing behaviour to be evaluated.

Customer ServicePotential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.
In the context of Vacuum Circuit Breakers, lead acid batteries can experience failure modes such as Positive Grid Corrosion, Plate sulfation, Dry out, and Soft Shorts.
The following are some common causes and results of deterioration of a lead acid battery: Overcharging If a battery is charged in excess of what is required, the following harmful effects will occur: A gas is formed which will tend to scrub the active material from the plates.
The lead-acid battery undergoes the following chemical reaction in a sulphuric acid electrolyte: PbO2 + Pb + 2H2SO4 <—————-> 2PbSO4 + 2H2 + 1⁄2 O2. In flooded batteries, the Hydrogen and Oxygen escape out. In contrast, in the VRLA batteries, the Hydrogen and Oxygen reactions are suppressed.
Sci.859 012083DOI 10.1088/1755-1315/859/1/012083 Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
If not maintained, flooded lead acid battery slowly losses water. If plates get dried, then there is no reversal for failure of battery. If gravity of electrolyte is not correct, battery works but losses its actual capacity faster over time.
